Subsea sensors are specialized devices designed to monitor and collect data from underwater environments. They can measure various parameters such as temperature, pressure, salinity, and water quality. These sensors are crucial for applications in marine research, oil and gas exploration, and environmental monitoring. These sensors are often deployed on subsea vehicles or buoys and can transmit data in real-time to surface stations. By providing valuable information about underwater conditions, subsea sensors help scientists and engineers make informed decisions regarding marine ecosystems and offshore operations.
